To all whom 2'3 may concern:

Be it. known that 1. WILLIAM SAME-ED zen of tlmlfniied Stu of Philadelphia. Stale certain new and Valves, of which Coorun, a citisiding in the ciiyand county or" Pennsylvunizn have invented useful Improvements in Flushingihe following is a specification.

My invention aims to provideen improved valve useful for various purposes, and of the type employed in the flushing oi water closets A slow-closing arrangement; is provided, and the operation in n general way is similar to previous valves of this type. The valve handle thrown and held tor a d d length oi tune, It thereupon role and it slov.-(-losing .ingeinent allows The vulve to move gnnlunlly to its it. lirsocutting oil the supply en tirelyorsull' ntly to brenl; the oi oi the usual siphon closet. so as to stop the siphonic notion. and subsequently allowing :1 small alter-flow lo fill the bowl to the desired extent. Various other improvements are referred to in dot-nil hereimi'ter.

The acconipsnying dr-.i\vings illustrate embodiments of the invention.

Figure l is en eleiutiou ol' the supply pipe side ol' he valve; Fig. 2 is n longitudinal section npproxinultely on the line 22 in Fig. 1; Fig. 3 u longitudinal secrion approximately on the line l :l in F' are sectional views of nl'ternzu'ive detail Relerring to ihe embodiment illustrated in the uccoinpanying druwi c the 'Ltlil or other tluid enters through the supply brunch and dischurges throi lt :t pipe si'rewed into the brunch ii. A vulvc propel is guided in u ('nge I) having vermin openings through which the \i'nter pr. s to the brunch ll when the valve is lilted. Supposing for example the valve to be liited to the point) indicated in dotted lines at. l", the water from the brunch A llows through the; sugcs or slots E, which taper toward the vnlve soul. [but is to soy, downward in the present, ca e, and thrmigh one or more sinull apertures l nour the lower end oi the cage. As the valve moves slowly .owuril its sent, the llow decreases gmduully by reoson oi. the grndnully (lei-reusing effective length of the slots E. and more .rupidly us the valve covers the tapering lower ends of the slots. \\'hen the valve passes the lower ends of the slots. the remaining flow is only through the Slllztll upertures F, which is not enough to supply the deuinnd oi the siphon. and the soul in the bowl will be broken. and the water in the upgoing leg of the siphon will drop buck into the bowl. The movement of the valve is sufliciently slow to allow enough \v'ltilll to lion through the apertures l to provide the desired retillin the bowl before the valve passes suid apertures. The cage 1) is prelembly lusscrcwing its lower end into n soclie't'G innuedintely surrounding the valve seat. ll. which inziv be provided with ii pricking .l' oi any usual it suitable Elpeeificaiiion of Lets'lgers Fatent.

In. order to effect the slow closure of the valve C, it is connected by Inc-nus of 2V stem K to it piston L of somewhat; larger diameter than the valve, which piston works in n cylinder M. Normally the net upward pressure of the water between the under side of the piston L and the upper side of the valve C. is more than counterbalan cod by the downward pressure of Water on cop oi the piston L. In order to operate the valve, the pressure in the cylinder M above the piston is withdrawn or relieved, which results in an upward n10vemerit of the piston and valve. The relief of the pres sure is cl'i'oci'c-d by ihe withdrawal of the water from the cylinder M. :i passageway being open for this purpose l e't .veen the cylinder and the discharge pipe. When this pussugcwuv then closed, Win01 from the branch A is admitted Ll-l u regulnble into to the upper side oi. the piston L. and acorn-ding to the nu e of admission the piston L and the valve are allowed to full slowly.

it is cssentiul to the durability of the apparatus in correct working order. that the pisron L shall lnake a good fit in its cylinder M, but not so right a lit as to become jaimncd. i n ordinary usage the apparatus is subjected to rough handling, and I propose to protect the cylinder M from becoming dented or otherwise disfreely sliding lit and one which is ii the same time per.-

icci'lv ti -hi and of mint (luruibilii. is made b 7 means a Q t) v of a line cup leather 0 on the under side of the piston. The cylinder ll and the outer casing N are preferably fastened by screwing l'ililu sockets P and Q on the upper end 01' Lhrcasing R, in which are formed the inlet ltllljl outlet brnnchcs A and For admitting writer to the upper sidioi the piston L or withdrawing water therei 1on1. the cylinder is open ut the upper end and communicates with the annular space T surrounding it.

The operation of the valve is dependent upon the control of the flow through the passages for relieving and for restoring the prcssure in the slow-closing cylinder Ill. A point of considerable .vzilue is the provision of :1 clnnnber U which forms a part oi each olsaid passages. the relief passage being controlled by a handle V in; one end, and the restoring passage being controlled by u nut W (Fig. 3) at the opposite end. This chumbor U is preferably formed as a part-oi the casting R, and lies in the angle between the admission branch A olthe valve and. the UPWlb'ld portion carrying the cylinder. It extends transversely to the plane of the branches A fill (TB, thus providing a very compact construction, and one in which the parts are inost; easily accessible For relieving the pressure ii -the cylinder M, the chamber U is provided with zi-perture'X communieating with the inmuhu space 1, and thence with the upper end of the cylinder.
